Basal Lamina are the Specialized Form of ECM01:03

Basal Lamina are the Specialized Form of ECM

4.0K
The basal lamina is a thin extracellular layer that lies underneath the cells and separates them from other tissues. The three layers of the basal lamina are lamina lucida, lamina densa and lamina reticularis. The basal lamina, a mixture of glycoproteins and collagen, provides an attachment site for the epithelium, separating it from underlying connective tissue. The framework of basal lamina has other essential proteins such as laminins mesh, perlecan, entactin, and type IV collagen.

Membrane Domains01:18

Membrane Domains

7.9K
The membrane domains concentrate specific lipids and proteins at one place within the membrane, which helps in cell signaling, adhesion, and other critical cellular processes. These domains can differ in size, composition, function, and lifespan.
Protein Domains
The membrane comprises a group of distinct proteins responsible for carrying out a cell's specific function. For example, the plasma membrane of the human sperm, or a single germ cell, contains a unique set of proteins in the...

What are Membranes?

208.1K
A key characteristic of life is the ability to separate the external environment from the internal space. To do this, cells have evolved semi-permeable membranes that regulate the passage of biological molecules. Additionally, the cell membrane defines a cell’s shape and interactions with the external environment. Eukaryotic cell membranes also serve to compartmentalize the internal space into organelles, including the endomembrane structures of the nucleus, endoplasmic reticulum and...

What are Membranes?

19.8K
A cell's plasma membrane demarcates the cell's borders and determines the nature of its interaction with the environment. Cells exclude certain substances, take in others, and excrete some others in controlled quantities. The plasma membrane must be flexible to allow certain cells, such as red and white blood cells, to change their shape while passing through narrow capillaries. These are the more obvious plasma membrane functions. In addition, the plasma membrane's surface carries...

Tissue Membranes01:27

Tissue Membranes

10.1K
A tissue membrane is a thin layer of cells that covers the outside of the body, the organs, internal passageways that lead to the exterior of the body, and the lining of the moveable joint cavities. There are two basic types of tissue membranes— connective tissue and epithelial membranes.
Connective Tissue Membranes
The connective tissue membrane is formed solely from connective tissue. These membranes encapsulate organs, such as the kidneys, and line our movable joints. A synovial...

Laminins are the Adhesive Proteins of Basal Lamina00:55

Laminins are the Adhesive Proteins of Basal Lamina

3.8K
Laminins are heterotrimeric proteins with high molecular mass found in the extracellular matrix. Each laminin molecule is composed of three chains, viz. alpha, beta, and gamma, coded by five, four, and three paralogous genes, respectively. Laminins are categories based on the compositions of the three chains.
In humans, the five forms of alpha chains are LAMA 1, LAMA 2, LAMA 3, LAMA 4, and LAMA 5. The four forms of beta chains are LAMB 1, LAMB 2, LAMB 3, and LAMB 4. The three forms of gamma...

  • Developmental biology
  • Biochemistry

Background:

  • Basement membranes (BMs) are specialized extracellular matrix sheets surrounding animal tissues.
  • Their structure arises from laminin and type IV collagen networks, stabilized by proteins like nidogen and perlecan.
  • BMs interact with cell surfaces via adhesion receptors and sulfated glycolipids.

  • To review the established and emerging roles of basement membranes in biological processes.
  • To explore the mechanisms of cell traversal across BM barriers.
  • To discuss the involvement of BMs in human diseases and future research directions.

Main Methods:

  • Literature review of established and emerging research on basement membranes.
  • Analysis of the structural composition and protein interactions within BMs.
  • Examination of the functional roles of BMs in development, homeostasis, and disease.

Main Results:

  • BMs are composed of dynamic, self-assembled polymeric networks of laminin and type IV collagen.
  • They serve critical roles beyond structural support, influencing development and tissue homeostasis.
  • Dysfunctional BMs are implicated in various human diseases, and cell migration across BMs is a key process.

Conclusions:

  • Basement membranes are dynamic structures essential for tissue integrity and function.
  • Understanding BM roles in development, disease, and cell migration is crucial for future research.
